Specification of Letters Patent.

Patented July 17, 1906.

Application filed January 3, 1905. Serial Nr 239 346| To all whom, it may concern:

} Be it known that I, PATRI K J. (burns, a citizen of the United States, residing at Scranton; in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Electric Railway-Motors,- of which the following is a specification.

This invention relates to improvements in electric motors of the type shown in my prior patents, No. 655,852, dated August 14:, 1900, and No. 725,675, dated April 21, 1903, in

' which twoor more armatures are arranged and having pole-pieces thereon adjacent to ing shown only upon one ole-piece within a surrounding field-frame, which is divided into two or more compartments by a transverse partition or partitions extending between adjacent armatures, each of said partitions forming a part of the magnetic circuit the armatures. In the present application a multiple motor of this character is arranged for railway traction purposes, the field-frame of the motor forming also a part of the truckframe.

In the accompan a plan view of a our-wheeled motor-truck embodying my invention, field-windings bewithin each compartment of'the fie d-frame. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a side elevation of the truck shown in Fig. 1.

Fig. 4 is a section on the line 4 4 of Fig.6, the armature being shown in elevation. Fig. 5 1s -a plan view of a four-wheeledmotor-truck,

the arrangement being the same as in Fig. 1, except that field-coils arearranged upon both pole-pieces in each compartment of the fieldframe. Fig. 6 is a similar" view of a sixwheeled truck. Fig. 7 is a plan view of a sixeach car-axle, each pair of armatures having a commutator common to both.

Referring to Figs, 1 to 4, incluslve, of the drawings, A indicates a rectangular fieldframe of iron or steel, having side bars a con nected by a central transverse partition a. and end bars a which are suitably connected to the end bars I) of an outer rectangular frame B. The side bars I) of the outer frame are suitably supported upon journal-boxes 1 at the ends of a air ofcar-a'xles 2 and 3 out side of the careels 4, and the side bars a of g drawings, Figure 1 is' wheeled truck, showing two armatures upon the inner frame are also preferably supported upon bearings 5, resting upon the axles at the inner sides of the Wheels.

Upon the car-axles and within the compartments C and C of the inner frame, formed by the partition a, are arranged armatures D, which are suitably secured to the axles so that the latter may be turned by the armatures. Pole-pieces 6 and 7, connected to the partitions a, project toward the armatures in the compartments 0 and'C, respectively, and opposing pole-pieces 8 and 9, respectively, are arranged upon the end bars of the fieldframeA at the opposite sides of the armatures.

with windings 10, and when current is passed through these coils or windings consequent poles areformed in the pole-pieces 8 and 9. As in my prior patents referred to, the magnetic circuits for both motors extend through through the side and end bars of the fieldframe A. v i 5 When the direction of the current in the windings is such as to produ'cepoles of opposite sign in the ends of thepole-pieces 6 and 7, and consequent]. poles of opposite sign in the both frames, as well as the partition (1/, then form arts of the magnetic circuit.

Fig. 1, except that field-windings are arranged upon the end ole-p'ieces 8 and 9 as well as upon the po e-pieces '6 and 7 se cured to the partition a, whereas in Fig. 1 the windings are upon the inner pole-pieces Fig. 6 a six-wheeled truck is shown, the frames'A and B being extended and the former having two partitions a, dividing the field-frame into three compartments 0, C, and 0*. Each partition carries pole-pieces 6f and 7 surrounded .by coils 10 and projecting in opposite. directions toward armatures D, arranged upon car-axles in the adjacent compartments. I 9 are arran ed upon the end bars of the frame A an surrounded by coils 10*, the same as'in 5. In Fig. 6 each partition 0 forms art of the magnetic circuit for two -motors, t e arrangement beingxsubstantially the same as in Fig. 5, except t at the frames end pieces 8 an 9, the side and end bars of.

The inner pole-pieces, 6 and 7 are provided the partition between the armatures and In ig. 5 the construction is the same as in Pole-pieces 8* and armatures.

a single commutator l3 suffices for each pair of Any desired number, of axles and partitions with pole-pieces between the axles may be added to the truck, and for such purposes, astransfer-tables, where extended axles are provided with more than two wheels to run on several tracks, more than two armatures may be placed on each axle, the pole-pieces on the transverse bars of the frame being correspon ly increased and the longitudinal partitions ei'ng also increased, if desired.

What I claim as new, and desire to secure by Letters Patent, is

1. In a motor-truck, the combination with axles having wheels thereon, armatures upon said axles and a main truck-frame supported upon the ends of said axles, of a field-frame having side rbars extending longitudinally of the truck-frame between the ends of the armatures and the wheels,-said field-frame having also a transverse partition arranged between each adjacent pair of armatures, polepieces upon each of'said partitions, and polepieces at the ends of the field-frame.

2 In a motor-truck, the combination with axles having wheels thereon, armatures upon said axlesfand amain trucka'frame supported upon the ends of said axles, of a field-frame secured to, the main frame, 'and'having side .-'bars extending longitudinally of the truckframe" between the ends of the armatures and the wheels, said field-frame having also a .fl 'tran sverse partition arranged between each adjacent pair of armatures, pole-pieces upon v axles having wheels thereon, armatures upon driving-axles, motor-armatures supported each of said artitions, and pole-pieces at the ends of the old-frame.

3. In a motor-truck, the combination with said'axles and a main truck-frame supported tupon the ends of said axles, of a field-frame having end bars secured to the main frame,

and having side bars extending longitudinally of the truck-frame between the ends of the armatures and the wheels, said field-frame having also a transverse partition arranged between each adjacent pair of armatures, pole-pieces upon each of said partitions, and prole-pieces upon the end bars of the field- 4. In amotor -truck the combination with axles having wheels thereon, armatures upon saidaxles, and a main truck-frame supported.

upon the ends of said axles, of a field-frame having end bars secured to the ends of the main truck-frame, side bars extendin between the ends of the armatures and the wheels, a transverse partition extending. be-

axleshaving wheels thereon, armatures upon said axles and arectan ular steel o'riron main truck-frame supporte upon the ends of the axlesat the outer sides of the wheels, of-arectan ular field-frame havin its end bars secure to the ends ofthe main truck-frame and its side bars extending between the ends of the armatures and the wheels, a transverse partition extending between each adjacent pair of armatures, pole-pieces upon each of said partitions and pole-pieces upon the end bars of the field-frame.
